FASTENEB-SETTING MACHINE.

January 22, 1923.

T 0 all "whom it may concern.

Be-it knownthatl, Planner R; Gmss, 1i citizen of the 'United States, residing at lV-ayland, in the county of Middlesex and 5 State ofMassachusetts, have invented certain Improvements in Fastener-Setting Mew chines, or" which the following description, in connection with tlreaccompanying drawings, is a'spec'ification, like reference characters on the drawings indicating like parts in the several 'fig'ures:

This invention relatesto fastener-setting machines andmore"especially to raceways for supplyin fasteners to the setting mechanism. The mvention is illustrated herein asembbdiedin an eyelet-setting machine of the typedisclosed in my copending application, Serial No. 323,164; filed September 11, 1919, of which this application is a division,

In the majority, if not all, of the prior commercial eyeleting machines provided.

with a' 'l'ropperand a raceway to supply the eyeletsfthe' entire length of the raceway as well as'the hopperandits'contents have constituted load on'the mechanism for reciprocating the delivery end oi the raceway to present the eyelets" to the setting mechanism, It has been proposed, however, to make-the raceway in two sections and to connectthe' sections by, a pivotal'joint, so that theup-per section and the hopper may remain stationary while the lowersection' alone is reciprocatedtopresent the'eyelets to the settingi mechanism. 1 In'the proposed jointed constructionssio provision has been made for adjust 7 way tofinsuie the necessary cooperative relation between" it and the" setting mechanism, althbughfitis 'of p'rimary and vital importaiicefto insure such cooperative relation becauseovithout' it the organization will not function at all.

Iii-view of the conditions described above air-object of: this i vcntion is'to provide an improved raceway? construction such that the advantages of relatively light load on the aeratin meclianismniay he obtained in ad-t inch to means torinsin-ins the necessary cooper i "relation beti'veen the delivery end of the raceway and the setting," mechainsm;

th'e'delivery endofthe race- I Divided and. this application filed Serial No. 324,184.

Accordingly a feature of the invention consists in a fastener-setting machine organization comprising a raceway the delivery end of which is movable relatively to its upper po tion, and means'for fastening the upper portion to 'tlieframe ofjthe fas tenor-settingmachine, said means having" provision for adjustment whereby the necessary cooperative relation between the delivery end and the setting mechanism may be established.

Since it is commonly necessary to substitute one raceway for another, as when changing from one size or style of fastener to another, or for some other reason to de tach the raceway from the machine, the attaching of the substitute raceway or the re attaching of the temporarily detached raceway involves in each case the problem oi? re-establishingr cooperative relation of the delivery end to the setting mechanism, for if the necessary adjustment is lost inciden tally to detaching the raceway considerable time would be lost in making new adjustment and in testing the assemblage to determine whet-her it is correct. In view of these considerations another object of the invention is to provide means by which an so adjustment once accurately established may be potentially preserved while the raceway is detached, so that when it is re-attached it will become again effective and thereby avoid the necessity of again determining what it shouldbe.

A. feature of the invention related to the latter considerations consists in providing the raceway with adjustable elements adapted to remain with the raceway as integral partsthereof and adapted to coo'perate with complemenl'alattaching means havmg no adjusting capacity. These adjustable elements, even when the racewayis'detached, never require a second adjustment for a given machine so long as they remain fixed relatively to the raceway, and they insure the desired cooperative relation regard less of the munber of times the raceway be detached and reattached. Another ad ntage of this feature is that any number of interchangeable raceways may be substitute done n21: anotherrepeatedly and for an indefinite number of? times with hnt'one of this figure is from the rear left-hand corner toward the front right-hand corner of the machine.

Fig. 2 is a perspective view partly in section of certain portions included in Fig. 1" as viewed from the front left-hand corner toward the rear right-hand corner of the machine.

F 3 is a vertical section of the portions forming the joint between the stationary section and the movable section of the race- Fig. at is a sectional view, in the plane indicated by line 4-401 Fig. 5, of the means forming the detachable connection between the movable section of the raceway and its operating mechanism.

Fig. 7 is a sectional view of the other one of said anchorages.

Fig. 8 is a bottom plan view of the hopper and the disconnectible devices for. operating the feeder therein.

' .riecording to the type of machine shown the raceway is arranged to deliver eyelets to an inserting; tool 10 above the work so that they will be inserted downwardly'into thework and clenched underneath. sorting tool is carried by a plunger which is arranged to slide up and down in stationary bearings one of which is indicated at 12.

The usual spindle 18 is provided for picking the eyelets from the raceway and holding them in position to be inserted and clenched. A port-ion of the work support is indicated at i l. Since the setting mechanism is mor fully shown and described in my aforesaid application Serial No. 323,164ethe showing in Fig. 2 will probably suilice for present purposes.

.ii feature of the raceway hereinafter described that only a relatively small part thereof is reciprocated to present eyelets to the tool 10. This feature according to the illustrated embodiment of the invention, is made possible by constructing the raceway in The insections and by joining them so that the uppresent the eyelets to the inserting tool. As

shown by Figs. 2 and 3 the sections 15, 17 are mortisedone intothe other and are con nected by a pivot member 18. The axis of the pivot member extends from side to side of the machine so that the delivery end of the raceway may move from front to rear. The delivery end of theraceway istherefore provided with an outlet extending toward the front of the machine to permit the d e tachment of the leading eyelet in consequence of moving the delivery end to the rear.

The mechanism for reciprocating the lower section of the raceway is shown by l ig. 1. The delivery end is moved to the rear by a cam 20 and to the front by a compression spring 21. The cam is afiixed to a shaft 92 andengages a roller 23 carried by a lever The fulcrum member of this lever is indicated at 25. The roller 23 is maintained against the cam by the spring 21 which surrounds a rod 26 connected to the lever 2 1. The upper part of the lever carries a. stud 2 7 by which pivotalconnection is formed with the rear end of a link 28. The forwardend of this link is pivotally connected to the lower racewayseetion by a stud To facilitate connecting the link to and disconnecting it from the raceway the forr-rard end of the link is formedwith a 'U-shaped portion 30 (Fig. 5) adapted to embrace an eccentric portion 81 of the stud 29. The link may thus be connected and pivot stud 27. The forward portion of the link projects beyondthe U-shaped portion sufiieiently to provide a handle 32, and this handle is made hollow to receive a spring follower the function of which is to latch automatically the link in coupled relation to the movable section of the raceway. The follower is adapted toyield to intentional coupling and uncoupling movement of the link to permit instantaneous disconnection and re-connection without requiring the use of a tool. The follower 33 is backed by a compression spring 34 and the latter is maintained under constant compression by a plug 35 secured into the end of the handle. The eccentric portion 31 of the stud 29pmvides for adjusting the delivery end of the raceway from front to rear, to give the coi l register of the leading eyelet with the .1 .ndle 13, butif greater adjustment is required it may be obtained from the pivot stud 27 which also has an eccentric portion. is shown by Fig. the righthand end of the stud 2 projects from the raceway and disconnected by swinging it about its rear on th stud to engage-the sides of the link to nuiintaintlie eccentric portion 31 in "register with the link while ad uSting' the raceway angnlarl about'the pin ll. The pivot stud.

. 2? at the rear end of the link is clamped by a split portion 38 of the operating lever, said split portion hz ving a clamping bolt 39, and the stud 27 hcingprovidec with a slot to receive a screwdriver so' that it may be 'tur for t -e purpose of efi ecting adjustment.

The fixres a? and 4-8 provided with holes for e-eeption of a screw stud 51, the adjust t; of the fixture d8 r latively to the raceway section loprovid for register of the holes notyithstandin iny slight inaccuracy of machining that would he .ely to occur. The stud-reee ving hole in the memher as tapped, and the stud 51 is t needed to screw into it. Then the stud is setup tightly its head is seated against one'side of the fixture e? and draws the fixture 48 The advantages of the construction described may be explained as follows: ;.F|Flll1'llllZ' that a ace- *oy is hein attachec l the first time. and

The eccentric bushing; e5 inay .then'he turned to adjust the delivery end of the raceway to the desired love. Then the raceway will be adjusted to place the delivery end in register-with th axis of the spindle if and while it is so held the screws 49 will be tightened to fix the raceway Section 15 relatively to the member &8. For the purposes or this adjnsiment the screw 86 (Fig. -l) will be loose to enable the raceway section 17 to slide along the stud 29. The shaft 22 rill then he turned by hand fixture.

until toe delivery end'ot the raceway moves and the stud 29, all ofwhich remain integral parts of, the raceway when the latter is detached, and since their adjustments are not disturbed by detaching the racewayfrom the machine they insure correct register when the raceway is replaced.

In practice it is customary to provide a plurality of raceways for each machine so that when it becomes necessary to change from one size or style of eyelet to another the operator has merely to substitute one raceway for another. Each raceway, having once been adjusted as describeu, need not thereafter undergo any chan e of adjustment in consequence of being replaced temporarily by one or more other raceua he eyelets are supplied to the upper section of the raceway by a hopper 52 containing a rotary feeder having a plurality,

of tufts 53 of bristles. This feeder and the ratchet wheel 5 1-, arranged under the hop 1 per, are connected by any suitable element extending through the bottom of the hopper. An oscillating arm carries a pawl 56 which engages the ratchet wheel to turn the feeder step by step in one direction, the pawl being maintained in engagement with the ratchet by a spring 57.

projects downwardly from the arm 55 to receive one end of a disconncctible connecting rod59. The other end of therod 59 is pivotally connected to an arm 60. Av tension spring 61 running from the rear end of the Connectirigrod downwardly to an anchorage on the arm 60 maintains the forward end of the rod normally in coupled relation to the pawl carrier 55, but when the raceway is about to be detached from the machine the connection between: the feeder and the connecting rod may be interrupted by merely depressing the forward end of the rod far enough to disengage it" from the pin The arm 60 is carried by one of the levers provided for operating another part of the machine. c
